Hi All, In a multi-layer PCB (12 Layer), How to determine the starting layer and routed layer of the signal via. Thanks and Regards, Jithindev

Internally we have recently discussed a useful feature called the ECL report. When we add the ECL property to a net(s) we can generate a report that looks as follows: This shows the data path of the Net MEMORY.RA15 including the via lengths. “*” means it is one of the end point of the net. “T” means T-Junction. NOTE: it does not generate report for hybrid signals (Traces + Power Plane) since there is limitation on calculating length shapes used for signal routing. To do this please follow these steps: Step 1) Add ECL Property to the Nets you want to examine. Step 2) Save the design to a temporary database. Step 3) From OS prompt type: report -v ecl .brd You could also use EXTRACTA to generate a file that can be loaded into a spreadsheet. Step 3) extracta .brd ecl_rep my_ecl_report.txt It is best to remove ECL Property from Nets when you are finished, so it is recommended to save a temporary database as per Step 2 above.
